Welding 1900's Cast Iron to Steel
Welding 1900's Cast Iron to Steel
(OP)
Anybody done this before? I am doing a storefront rehab where there are 2 nice 1900's archiectural cast iron columns. Span is very small. We are casting new conc footings with plate. Any important considerations welding a-36 steel to the old cast iron?
Thanks
Thanks

Is it not at all possible to use a bolted plate connection?

You need to do some testing to determine what kind of casting you have...
1. White iron is generally considered to be unweldable; Tamboli advocates looking at alternative connections if this is found.
2. Preheating is almost always required when welding cast iron (refer to my previous post re HAZ).
3. Any welding process may be attempted, however the electrode used should be a cast-iron electrode as specified in AWS A5.15.
4. The weldment must be permitted to cool slowly. (Did I mention HAZ?). Since you're dealing with a structural load bearing member (even though the loads are presumably small), you need to be concerned about embrittlement and brittle fracture.
Tamboli advocates testing the welding procedure before use, and lastly recommends the same things I do: A welding expert should be consulted.
Good luck!
